The controller can be integrated into a data network using an optional RS-485 (terminals R+ and R-) interface or an optional Profibus
DP interface(only model
RWF55.6x terminalsC1-C2-C3-C4)
( bold = factory settings)
Manual control :
In order to manual change the burner load, while firing keep pushing the ESC button for more than 5 s; on the lower green display
Hand appears.
using the UP and DOWN arrows, the load varies.
Keep pushing the ESC button for getting the normal operation again.
NB: every time the device shuts the burner down (start led switched off - contact 1N-1P open), the manual control is not active.
Device self-setting (auto-tuning):
If the burner in the steady state does not respond properly to heat generator requests, you can activate the Device's self-setting fun-
ction, which recalculates PID values for its operation, deciding which are most suitable for the specific kind of request
Follow the below instructions:
push the
UP and DOWN arrows for more than 5 s; on the green lower display tUnE appears. Now the device pushes the burner to
increase and decrease its output. During this time, the device calculates PID parameters ( Pb1 , dt and rt ). After the calculations, the
tUnE is automatically deactivated and the device has already stored them.
In order to stop the Auto-tuning function while it works, push again the UP and DOWN arrows for more than 5 s. The calculated PID
parameters can be manually modified following the previously described instructions.
